Apparatus for producing joined-resin product and method for producing joined-resin product

Abstract

Provided is an apparatus for producing a joined-resin product in which two or more resin members are joined. The apparatus includes: a surface treatment mechanism comprising an electrode unit generating ionized gas, and a member holding mechanism arranged at a position separated from the electrode unit by a space and holding the resin member, the surface treatment mechanism activating a surface to be joined of the resin member held by the member holding mechanism, by the ionized gas generated by the electrode unit; and a joining mechanism bonding the two or more resin members together where at least one of surfaces to be joined facing each other is activated by the surface treatment mechanism, at the respective surfaces to be joined.

The invention claimed is: 
     
       1. An apparatus for producing a joined-resin product in which two or more resin members are joined, the apparatus comprising:
 a surface treatment mechanism comprising an electrode unit generating ionized gas, and a member holding mechanism arranged at a position separated from the electrode unit by a space and holding the resin member, the surface treatment mechanism activating a surface to be joined of the resin member held by the member holding mechanism, by the ionized gas generated by the electrode unit; and 
 a joining mechanism bonding the two or more resin members together where at least one of surfaces to be joined facing each other is activated by the surface treatment mechanism, at the respective surfaces to be joined, 
 wherein the surface treatment mechanism is equipped with a rectification plate surrounding a space between the member holding mechanism and the electrode unit. 
 
     
     
       2. The apparatus for producing the joined-resin product according to  claim 1 , wherein
 the electrode unit is a facing anode and cathode, 
 the member holding mechanism is configured to hold the resin member so that a space generating the ionized gas between the anode and the cathode and the surface to be joined of the resin member separately face each other by a space, and 
 the electrode unit comprises a gas supply nozzle supplying gas for generating ionized gas toward the resin member held by the member holding mechanism through the space between the anode and the cathode. 
 
     
     
       3. The apparatus for producing the joined-resin product according to  claim 2 , wherein the cathode comprises magnets inside the cathode, the magnets forming a magnetron magnet field in the space between the anode and the cathode. 
     
     
       4. The apparatus for producing the joined-resin product according to  claim 2 , wherein a grounded metal mesh is provided between the space between the anode and the cathode and the resin member held by the member holding mechanism. 
     
     
       5. The apparatus for producing the joined-resin product according to  claim 1 , wherein:
 the electrode unit is a facing anode and cathode, and 
 the rectification plate is electrically insulated from the anode and the cathode.
